Steel Sample Number of Cycles: [Enter Value] Amplitude Stress: [Enter Value] MPa

Aluminium Sample Number of Cycles: [Enter Value] Amplitude Stress: [Enter Value] MPa

Step 4: Results. S-N Curve for steel and Aluminium

• Endurance Limit for Steel is ~320 MPa.
• Fatigue strength for Aluminum alloys is ~163 MPa @ 10^7 cycles since the materials doesn’t exhibit no endurance limit.
